Aqueous coating composition and floor polishing composition |
(57) An aqueous coating composition useful as a floor polishing agent is disclosed. The
composition comprises (A) an aqueous dispersion of a copolymer obtained by the emulsion
polymerization of (a) an ethylenically unsaturated carboxylic acid monomer, (b) a
(meth)acrylic acid alkyl ester monomer, and (c) other monomers polymerizable with
the monomers (a) and (b), (B) an unsaturated monomer curable with energy rays, and
(C) a photoinitiator. The floor polishing agent containing the aqueous coating composition
exhibits excellent delamination properties and dry buff applicability.
